New study reiterates basic elementary school science, says kids who catch cold without vaccines develop natural immunity – zoohousenews.com

(Natural News) Swedish researchers have discovered the obvious about the human immune system: when a person “catches” a cold and recovers, he or she develops enduring natural immunity to coronavirus.
The common cold is a type of coronavirus, in case you didn’t know. And if you’ve ever had a cold, especially as a child, your immune system already knows how to fight off coronaviruses, including the Wuhan coronavirus (Covid-19).
For their study, published in the Proceedings of the National Academy of Sciences (PNAS), the researchers examined 48 blood samples from children between the ages of two and six, and 94 samples from adults between the ages of 2 and 4 years, 26 and 83. They also examined Blood samples from 58 people who had recently recovered from Covid infection.
Apparently, it came as a surprise to the experts at Karolinska Institutet, who led the study, that previous coronavirus infections train a person’s immune system to fight off coronaviruses naturally – and without the need for “vaccines”.
They found that cross-immunity to Covid is formed when memory T cells, produced by more common coronaviruses, develop after natural infection. Blood samples from children collected before the onset of the “pandemic” show that these memory T cells are indeed responding to cells infected with SARS-CoV-2.

Natural immunity to coronaviruses develops as early as two years of age
There are four different coronaviruses that are primarily responsible for seasonal cold systems, the researchers said. And exposure to all of these coronaviruses stimulates an immune response that persists post-Covid.
Even T cells previously activated by the OC43 virus, for example, are responding against SARS-CoV-2, demonstrating what elementary school science taught children from an early age: that natural immunity develops after natural exposure.
“These responses are particularly strong early in life and become much weaker with age,” said Annika Karlsson, the study’s corresponding author and research group leader in the Department of Laboratory Medicine at Karolinska Institutet.
“Our results show how the T-cell response evolves and changes over time and may guide future surveillance and vaccine development.”
The next step for this particular area of research is to conduct analogous studies in younger children, older children, adolescents and young adults to more closely follow how the immune response to coronaviruses evolves at each stage of life from childhood to adulthood.
Similar research, published in The Lancet in February, also found that naturally contracting and recovering from Covid provides durable immune protection against further Covid infection.
The researchers analyzed 65 different natural immunity studies and found that the average effectiveness of natural immunity is at least 88 percent against hospitalization and death for at least 10 months after infection with all Covid strains and variants.
“I had Covid in 2021,” one commenter wrote in response to these studies. “I don’t have any comorbidities – it was tough, worse than the flu. I treated myself and was fine after about a week. I’ve never had any of the vaccines, I’m not social distancing, I don’t wear a mask, I don’t use hand sanitizer and I work with the public and I know I’ve been exposed multiple times as recently as last week and everyone in my circle has tested positive.”
“All I had was a sore throat,” this person added. “I can’t help but believe that I have long-term immunity to early contracting Covid. The people around me who have had confirmed cases in the past have also had milder symptoms to varying degrees.”
